No way my gravestone will go here! (4,2,4,4)
I believe the answer is:
over my dead body
'no way' is the definition.
(I've seen this before)
'my gravestone will go here' is the wordplay.
I cannot quite see how this works, but
'my' is within the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for over my dead body that I've seen before include "Where grave words may be spoken" , "Where earth may be scattered" , "Not if I can help it!" , "should one grieve here?" , "No way" .)
